Application of Improved Double Half-word Recognition Method in Water Character Recognition System
Xu Pin · 2016
In water character recognition system,it is hard to recognize the character when upper and lower half-word is incomplete because of the usual situation of partial carry caused by meter mechanical structure.To solve the problem,an improved double half-word recognition algorithm is proposed in this paper.Firstly ten standard complete two-character templates are made.Then double half-word is cut from the two-character templates based on the incomplete double half-word which is waited recognition by segmentation and the improved Hausdorff-distance template matching is applied to pattern match.Finally the character is determined by comparing the ratio of upper and lower halfword.It approves that this improved algorithm shows good recognition to this type of double halfword and improves effectively the character recognition power of automatic reading meter system in the experiment.
